This is a problem you will to take to a shop, If you are mechanically inclined I can help you, but if not I would not mess with it, it could be the button or it could be the controller and could even just be a fuse, check the fuse and if you don't find the fuse blown then let me know if you have a volt meter and what to test this yourself. You are going to be working around the air bag too and if you probe the wrong wire while testing you could break your arm or leg by deploying the air bag by accident. Or your neck.

pull the plastic cover off the top of the engine and check where the cable from the cruise control connects by the throttle body. There is a plastic connector that might be broken. i had the same problem and a piece of tape fixed it for me but you can replace the part if your picky.
